Some more information could help.

Self reflection on personal failings?

• Stormlight Archive series starting with the way of kings

Many interesting perspectives but I think Dalinar’s character in the series would resonate with what you’re asking about.

Not that there aren’t many such views such as Kaladin and others with some insights into struggling with depression, feelings of inadequacy, weight of the world on you and fears of letting people down.

Insights into other perspectives?

• The Murderbot Diaries (already mentioned here and I can’t recommend it enough)

• Klara and the Sun

• written wholly from the perspective of a self aware machine and what it means to be a girls best friend, what it means to have purpose and how things change

Learning self acceptance or to appreciate how one fits into the world?

• The Rosie Project. An interesting story written from the perspective of somebody who is neurodivergent but doesn’t realize they are.
